exams that follow are more difﬁcult than actual past exams. (We think it’s a good idea to practice
on problems that are a little harder, on average, than the real thing.) So don’t be discouraged if you
don’t do too well on these exams. Do all of the problems that you don’t get right a couple of days
later under time pressure to make sure that you have learned how to solve them. These practice exams follow the format of the actual exams in 2008: 35 questions in three hours. The
actual exam will be in CBT format. Several of the questions (perhaps ﬁve) will be pilot questions
that will not be graded, but you will have no way of knowing which ones they are. When you take these exams, stick to the time limit and simulate exam conditions. Questions for Practice Exam 1 1. Harvey is repaying a loan of 1000 with annual payments of 120 for 10 years followed by annual

17<t< 18 Thus, at the end of 18 years (on 12/31/20), there is 5000.04)18 = 1012.91 in the 4% account. Then
12.91 is “withdrawn” and “deposited” in the 5% account. Each year thereafter, 4% x 1000 = 40 is “withdrawn” from the 4% account and “deposited” in the 5% account. The account value on
12/31/2032 is the sum of: (a) 1000 (b) The AV at 5% of 12.91 for 12 years (from 12/31/2020 to 12/31/2032), or 12.91(1.0513) =
23.18. (c) The AV at 5% of annual “deposits” of 40 for 12 years (“deposits” on 12/31/2021 to
12/31/3032), eraosEl at5% = 636.69. Thus, the AV on 12/31/2032 is 1659.87. ANS. (E) 15. We know that dc) < 6 < in) < 1' at the same rate of interest. This fact permits us to order the given
rates. For example, if i = .04, 8 < .04 and hence a force of interest equal to .04 implies an annual
effective rate greater than .04. By similar reasoning I < [[1 < H < IV. ANS. (A) 16. Although we are not given the term of the bond, the redemption value, etc., we can easily answer this
question by making use of the fact that the write downs are in geometric progression with common
ratio (1 + i). If the write down in the 15th year is 0.80, the sum of the write downs in the ﬁrst 9
years is given by: X = 0.130094 + v13 +   + W) at 4%
= — (15') = 4.89 ANS. (B) Note: We did not even have to know the frequency of coupon payments. This is because the write
down in any periodic coupon is (1+i) times the write down in the periodic coupon paid one year
earlier, so the sum of the write downs in each calendar year also forms a geometric series with
common ratio (1 + i). 17. Using the “block payment” approach (see Section 3c of this manual):

a one—year deferred 9payment annuity, etc., plus the PV of a 9year deferred lpayment annuity. ii —10v10
This adds up to the PV of an increasing 10—payment annuity, which is L. Thus, the same
result as above can be obtained by general reasoning (if you are lucky enough to see this under exam
conditions). The PV of the payments is:

We now have to deduct the AV at time 2 of the withdrawal of 1000 at time I. Here we have to be
careful not to fall into the variable force of interest trap. (See Section lg of this manual.) The AV
